' DIRIGIBLE HEADLIGHT.

Appcaton filed April 24, 191e,

To all wlw/n it may concern:

Be it known. that l, Liso .'l'. Noci zs'raun, a citizen of the United States, residing at San Antonio.` in the county of Bexar and State o'l" Texas, have invented certain new and useful 11n provements in Dirigible Vi-leadlights, ot' which the 't'ollowing is a specification, reference being had therein to the accompanying drawing.

One ot the objects ot' the invention is to provide an improved lamp bracket having means tending to automatically el'l'ect centering and prevent vibration. Another object ci the invention is to provide in a 1nechanism oit the sort re'lierred to improved connecting devices between the lamp brackets and the steering mechanism oi the automobile. Another object is to provide a general improved arrangement and construction ot' the parts of a mechanism ol" this class.

Referring to the drawingsll'igure 1 is t 'front view oit' an automobile having attached thereto devices embtnlying my invention.

Fig, 2 is a plan view oie seme ot' the parts shown in Fig. 1.

Fig, 3 is an. enlarged sectional view taken through one et the lamp brackets. l

Fig. 4 is a fragmentary sectional view showing the means or comiecting the lamp controlling devices to the automobile steering mechanism. i

Fig. 5 is a tragnientar)v view slur-wing in detail somo ot the parts illustrated in Fig. Yl-.

In the drawings l have shown some ot the parts at the 'troni' end olf an automobile, they being su'tlicient lo illustrate the manner of applying my invention to the lamp system of such a vehicle. lt is unnecessary to describe in detail, paris ci the automobile proper, it being suiiicient to say that 1 indicates the front bolster or cross sill part that supports the front. end ot the vehicle body; and that 2 indicates the `trout axle upon which the sill 1 and the body bear through the interposed transverse ilront| springs. 3, 3 are the front wheels which are carried in more or less the usual wav by means of the stud spindles each on a bell lever or a knuckle carrier pivotedat The rearward projecting arm ot each lever or knuckle is connected with the other by means of the cross rods l pivoted to each.

6 indicates the link or pitinan which transmits the pull or thrust 'from the manual Specification of Letters Patent.

steering devices to the wheel spindles` so as to rock them in horizontal planes in steering in the usual way. This steering rod or link G extends from one side part way across the mechanism, and its inner end is adapted to vibrate vertically in relation to the axle. The steering shatt is indicated by 7. lt is mounted in the post 8 and is provided with a hand wheel 9 accessible to the driver.

10 is a sleeve or tube which is tightly secured to the link or piiman (i b v means oli a clamp having the halt sleeves 11 which are zttached to the pitman near its inner end. Each ot these has at each side ot' its center a projecting section lll. The exterior surface olf each ot these sleeve sections is tapered and the two sections have registering tapering threads. The sleeve Ill) at its rear end has an internal tapering thread which engages with the sleeve halves 11 on the front side oi the clamp.; and on the rear side use is .made ot a nut 1Q, also provided with an internal tapering thread. `When the sleeve 10 and the uutl 1'2 are forced tightly to place thev bind the clamp halves 11 tightly to the rod G and serve to prevent slippage in either direction along the rod.

The other end oit.' the sleeve 1l) is pivotallv connected to the two lamprods 111.-. Each of these, at its inner end. has a pivot piece 141-, each of which is ral'ibeted and apertured, as shown at 11i- A pivot pin or bolt ll passes through the two rabbet-ed parts oi the pivot pieces and engages with the sleeve l0.

The rods 14, at their outer ends, are pivoted to the lower ends of the shafts or spindles 15, which carry the brackets and lamps. Each of these is carried by a stationary tubular standard 1G having an arm 16a rigidly secured by the threaded part 16b to a suitable part of the main frame. The upper part of each tubular standard is shaped to provide a sharp V-shaped socket or recess. The upper part of the standard has a central cylindrical aperture. The vertical shaft or spindle 15 has its upper part reduced in diameter as shown at 15, this part passing' through the central aperture in the standard. 15b is a spring interposed between the shoulder in the bracket at 17 and the shouldered lower part of the shaft 15. Preferably there is a plug-like block fastened in the upper end of the standard tube to provide the shoulder at 17 and also to provide'the sharply cut il-shaped socket or recess at the upper. end of the stem. The upper end part of the shaft 15 is still further reduced and threaded as at 15d. The lamp bracket 18 has the fork arms 18b to which the lamp is secured in any preferred way. At the lower ends these arms are integral with, or rigidly secured to, a central boss r art 18C, which has a central vertical aperture. The upper part 15d of the spindle 15 passes through this aperture and the spindle isrigidly secured to the bracket by means of the nut 15C.

The lower edge of the hub part 18c is formed to have bottom surfaces which converge downward at a sharp angle corresponding to the recess at 17l in the upper end of the standard.

A spring 15b tends to hold the convex bottom part of the hub 18C snugly in the V- shaped recess, but upon the application of power to the spindle retention of the spring is overcome sufiiciently to permit the bracket to be turned.

At the lower end of the spindle 15 there is a crank arm 2O extending outward to a point suitable for pivotal attachment to the above described rods 14.

The crank arms at the lower ends of the lamp spindles are preferably carried to points somewhat behind the axial vertical plane of the axle; and the vertical aXes of the lamps are brought back so as to be positioned as near as possible to the same plane. This arrangement brings the vertical axes of the cuter ends of the operating rodsl near to the vertical plane of the axis of the pivot which connects them to the hinging device at 10.

What claim is:

1. ln a vehicle ofthe class described, the

combinationV of the lamps, the lamp stems,

the seats for the stems holding the lamps substantially rigidly against rotation when in normal position, and the vertically vibrating steering rod, of the lampbperating rods pvotally connected to the steering rod near its vibrating end and connected to the lamp stems at points near the transverse vertical plane of their connection with the steering rod, substantially as set forth.

2. In a vehicle of the class described, the combination with the lamps adapted t0 swing on vertical axes, the lamp-rotating crank arms, and the vertically vibrating steering rod for transmittingsteering movement to the wheels, of the hinge device secured adjustably to the steering vrod near its vibrating end, and the lamp-operating rods pivoted to the hinge device and pivotally connected to the lamp cranks at points approximately in the vertical plane of their connection to the hinge device.

3. The combination with the frame, the front wheels and the steering mechanism of an automobile, of two lamp-carrying spindles mounted on opposite sides of the frame for oscillation about vertical axes; operating arms secured to the spindles, a clamp engaging a movable rod of the steering mechanism and comprising two halfsleeves each provided with opposite tapering threaded half-sections, the threads of the corresponding half sections of the two halfsleeves registering, a sleeve having internal tapering threads which engage the threads of one pair of half-sections, a nut having tapering threads engaging the other pair of half sections, and connections between said sleeve and the operating arms on the spindles.

The coirbination with the frame of an automobile, the front wheels and the steer ing mechanism having a substantially horizontal transverse Operating rod, of two lamp-carrying spindles mounted on opposite sides of the frame for oscillation about vertical axes, operating arms secured to the spindles, a Centrally located clamp engaging the said operating rod of the steering mechanism and comprisingtwo half-sleeves each provided with opposite tapering threaded half-sections, the threads of the corresponding half sections of the two half-sleeves registering, a sleeve extending forward from the rod having internal tapering threads which enofage the threads of one pair of half-sections, a nut having tapering threads engaging the other pair 0f half sections, and transverse links pivotally connected at their inner ends to the said sleeve and at their outer ends to the operating arms on the spindles. l

In testimony whereof I aflix my signature in presence of two witnesses.
